1 Claim.

The present invention relates to molds for smoking, cooking or otherwiseprocessing sausages and other meats.

The principal object of the present invention is to provide a suitableclosure fastener for a mold of the type mentioned. During the smoking orother processing of sausage and similar meats, in molds, a considerablepressure is applied to the closure of the mold, and'it is found thatunless some positive interlocking elements of suflicient rigidity areprovided, the mold will frequently spring open resulting in the loss ofits contents. At the same time the closure fastener must be of extremelysimple construction, and capable of rapid and certain operation in orderto provide for the economical and effective accomplishment of theresults desired. The pres-- ent invention attains these objects by meansof a closure fastener positive in operation and at the same timeextremely simple and inexpensive of construction as well as operation.

In the drawing:

Figure i is a perspective of a mold having a closure constructed inaccordance with this invention.

,Figure 2 is an enlarged perspective of a portion of the interlockingelements of the closure.

Figure 3 is an end View of a mold provided with a closure in accordancewith this invention.

The mold consists of two right-angular sections l 2 hingedly securedtogether at 3. The sections i and 2 are constructed in the usual mannerof right-angularly bent cross wires 4, and of cting longitudinal wiresin accordance vvuh the usual construction of molds of this type.Alternate wires 4 of the section 2 are bent to form hooks which when thesections are in closed position as shown in the drawing, engage over theedge longitudinal wire 'l of the section l, said wire 'i beingpreferably unitary with the top and bottom wires i of said section I.The hooks S provide a slight frictional engagement with wire 'i and thusserve as a preliminary or temporary locking means. Before the cooking orprocessing commences, however, the sections are interlocked by means oithe mechanism next to be described.

Beyond the hooks 5 the alternate wires t of section 2 extend outwardlyto form securing projections or standards 8 for a cross rod 9 which issecured to the free ends of the standards 8 by welding or other suitablemeans. Secured to the section 2 are four wires or rods It whichterminate in loops or eyes I I. Mounted so as to slide in the eyes il isa lock rod E2, one end of which is bent at right angles to the mainsection 'position shown in Figure 2.

of the rod and terminates in a loop or eye I3 which engages slidablyaround the rod 9. Secured by welding or other suitable means to thesection I are wires forming rigid hooks I4. 'Ihe hooks i4 are sopositioned with respect to the 5 rod I 2 slidably carried by section 2that when the sections are in closed position, said hooks engage saidrod I 2 so as to provide a positive interlock between the sections. Inorder to permit the relative movement of the sections this interlock 10may be released by reason of the offsets or bends l5 formed in the rodl2, said bends being positioned in alignment with the hooks when desiredby the slidable operation of said rod. In Figure 1 the rod I2 and hooksI4 are in relative position 15 to provide a positiveI interlockingclosure for the sections. In Figure 2 the rod I2 having been moved tothe right has brought the bends I5 into alignment with hooks I4; thehooks are therefore permitted to pass the rod thus allowing the openingof the sections. The rod .I2 is provided with a right angled terminalextension I6 which serves as an operating handle for the sliding of therod in either direction, a loop I'I in the shank of said handleproviding clearance for the end standard 8.

From the foregoing description, it is thought that the nature andoperation of the present mold closure will be apparent to those familiarwith the art.

When it is desired to move the sections I and 2 relative to each other,the rod I2 is slid into the In this movement the rod operates throughthe eyes II and by its own eye or loop I3 traveling on the bar 9. In 35this position the hooks I4 may freely pass the lock bar I2, and thesections i and 2 may be operated to open or close the sections. When thecontents have been provided in the mold, the sections are brought toclosed position, in which position they may be temporarily held by thefrictional engagement of the hooks 6 over the wires l. Positive andpermanent closure for processing is then provided by sliding the lockrod I2 to the left, which brings the straight por 45 tions of the rodinto engagement behind the hooks i4. When thus interlocked, the sectionsare enabled to stand pressure limited only by the strength of thematerials of which the several parts are made.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

A closure fastener for hinged sections comprising a series of eyes nearthe edge of one of said sections, a rod xedly secured along the edge ofsaid section beyond said eyes, a lock rod slidably mounted in said eyes,an angular extension at one end of said lock rod, an eye at the end ofsaid extension in slidahle engagement around said Xed rod, an angularhandle extension at the other end of said lock rod, said handleextension having a loop adapted to engage slidably the end edge of saidsection to cooperate with the extension and eye at the opposite end ofsaid lock rod, said lock rod having a series of bends to provideclearances for a series of keepers at one position of longitudinaladjustment of said lock rod, and straight portions adapted to slidebehind said keepers to secure the sections together.
